After installing the Schedule React license is no longer valid

in my project I have this package json:

    "@syncfusion/ej2-base": "^20.4.40",
    "@syncfusion/ej2-data": "^20.4.40",
    "@syncfusion/ej2-grids": "^20.4.40",
    "@syncfusion/ej2-notifications": "^20.4.40",
    "@syncfusion/ej2-react-barcode-generator": "^20.4.40",
    "@syncfusion/ej2-react-charts": "^20.4.40",
    "@syncfusion/ej2-react-dropdowns": "^20.4.40",
    "@syncfusion/ej2-react-grids": "^20.4.40",
    "@syncfusion/ej2-react-inputs": "^20.4.40",
    "@syncfusion/ej2-react-navigations": "^20.4.44",
    "@syncfusion/ej2-svg-base": "^20.4.40",
Later I have added:

    "@syncfusion/ej2-react-schedule": "20.4.44",

but after have inserted react-schedule my free license is not valid. Do you have some suggestions?

Hi Alberto,


Greetings from Syncfusion support.


We have investigated your reported issue at our end based on the screenshot provided. We suspect that the issue occurs due to referring to the additional packages in the package.json file. If you are utilizing the React components, kindly refer only to the Syncfusion react component packages in the package.json file and remove other Syncfusion packages. Apart from the React packages, you can remove the following packages in the package.json file to resolve your reported issue.


Kindly remove the following packages:








Please follow the below steps, once the changes are done.


  •  Delete the @Syncfusion folder from node_modules and the package-lock.json file from the root folder.
  • Clear npm .cache file at your end.
  • Update our packages to the same major version. For example, if your utilizing version like (i.e. v20.4.XX) use the  same version for all the Syncfusion components in the package.json file.
  • Run the ‘’npm install” command to install the node_modules.        

Please get back to us if you need further assistance.
